Not a fan of introducing an unused function and then the calls afterwards. Makes it harder to find possible improvements.

This is meant after D795, to change from UK format to US format.
leper had comments there saying we should have an international English format and then US can have its own translations. I'm not sure all the details will work out, but that should be the first approach rather than this patch.

Wait, we're talking about changing the default english strings from en_US to some international english (what definition?), then the scope of the change would be global.
Then all english strings have to be rechecked and translated to "international english", not only these 4 functions.

Also leper mentioned:

if you find someone that will and sees the possible confusion for most (all?) other translations as worth it, I'll not complain.
